Smartphone apps may be secretly taking screenshots of your activity and sending them to third parties, a study has found. This is particularly disturbing because these screenshots - and videos of your activity on the screen - could include usernames, passwords, credit card numbers, and other important personal information, researchers said. "We found that thousands of popular apps have the ability to record your screen and anything you type," said David Choffnes, a professor at Northeastern University in the US.
